In this course, you will learn Lua: Programming From Zero to Hero, Lua is a lightweight, high-level, multi-paradigm programming language designed primarily for embedded use in applications. It is cross-platform, as its interpreter of compiled bytecode is written in ANSI C, making it highly portable. Lua is known for its simple procedural syntax with powerful data description constructs based on associative arrays and extensible semantics. It supports procedural programming, object-oriented programming, functional programming, data-driven programming, and data description. Lua is dynamically typed, runs by interpreting bytecode with a register-based virtual machine, and has automatic memory management with incremental garbage collection, which makes it ideal for configuration, scripting, and rapid prototypingLua Syntax and Basics: Understanding the fundamental syntax and constructs of Lua, such as variables, data types, and operators.Control Structures: Learning how to use conditional statements and loops to control the flow of the program.Functions: Defining and invoking functions to create reusable code blocks and manage code complexity.Tables: Working with Lua’s primary data structure for organizing and storing data.Modules and Packages: Organizing code into modules and using packages to extend Lua’s capabilities.Error Handling: Implementing error handling and debugging techniques to create robust Lua applications.File I/O: Reading from and writing to files to handle data persistence.Metatables and Metamethods: Using advanced features of Lua to customize the behavior of tables.Coroutines: Understanding and utilizing coroutines for cooperative multitasking.

This course provides a clear and structured introduction to Operating System concepts, starting from the basics and moving towards more detailed topics. It is designed to help learners understand how operating systems work and how different components interact within a computer system.In this course, you will study key topics such as process management, memory management, file systems, device management, and CPU scheduling. Each concept is explained in a simple and easy-to-understand manner with practical examples to improve clarity and build confidence step by step. The course also introduces important topics like threads, deadlocks, and synchronization to build a strong understanding of system behavior.Basic usage of Linux and Windows operating systems is also covered to give you a practical view of how operating systems function in real environments. This helps learners connect theoretical concepts with actual system operations.This course is suitable for students, beginners, and anyone interested in learning the fundamentals of operating systems. It can also be helpful for those preparing for exams or technical interviews.By completing this course, learners will gain a solid understanding of operating system concepts and be able to relate them to real-world computing systems effectively and accurately in practical situations.

This course is intended for C++ developers who wish to update and refresh their C++ skills, especially those who have been using other languages for several years. You will learn about the new language features, how they make programming in C++ less painful and more productive, and how to use them idiomatically,If you're used to traditional C++, Modern C++ will feel like a different language. It is safer, more expressive and more efficient. With Modern C++, you no longer need to work with explicit pointers to memory, which you have to allocate and release yourself. Complex loops can be greatly simplified, or even avoided altogether. Better abstractions remove the amount of "boilerplate" code you have to type in, leaving you free to concentrate on the problem you are trying to solve.Modern C++ will reduce your development time and make your code easier to maintain and more likely to be correct and efficient. It avoids many situations which cause undefined program behaviour, resulting in less time spent on debugging and fewer defect reports.The course begins with a review of C++ as of the 1998/2003 standards, including exceptions, templates and the Standard Template Library. If you have not used C++ for some time, this will allow you to revise and refresh your existing knowledge.We then cover the changes in 2011 and 2014, starting with the core language and the standard library. Important new features such as lambda expressions, move semantics and multithreading have their own sections. Another section covers the most important features in C++17, which is the most recent widely-used version in industry. Finally, there is some advice on how to use good practice when writing Modern C++ code.Each lecture contains a demonstration of the features being covered and has downloadable resources: the source code used in the video, exercises and solutions for the exercises. These are fairly simple and test your understanding of the topic you have just learnt.There ar
